5 Reasons Your Air Conditioner Gets Dirty & How to Prevent It

At Airview AC, we help homeowners across McKinney, TX, and nearby cities keep their HVAC systems running smoothly. If your AC isn’t cooling, dirt and debris could be the culprit.

Here are the top five reasons air conditioners get dirty and what you can do to keep yours in peak condition. If your system needs professional cleaning or maintenance, call Airview AC today!

1. Dirty or Clogged Air Filters

Your air filter is the first defence against dust, pet dander, and airborne particles. When filters aren’t changed regularly, they become clogged, restricting airflow and causing your AC to work harder. This extra strain can lead to overheating and premature system failure.

Prevention Tip: Check your air filter every month and replace it at least every 1–3 months. If you have pets or allergies, consider upgrading to a high-efficiency filter. Need help finding the right filter? Call Airview AC—we’ll guide you to the best solution!

2. Debris Around the Outdoor Unit

Your AC’s outdoor condenser unit is exposed to the elements, meaning leaves, dirt, and grass clippings can quickly accumulate around it. When airflow is restricted, your system has to work harder to expel heat, reducing efficiency and increasing wear and tear.

Prevention Tip: Keep at least two feet of clear space around your outdoor unit. Trim back shrubs, sweep away debris, and schedule a professional cleaning at least once a year. Not sure how to clean your AC safely? Call Airview AC for expert maintenance services!

3. Leaky or Dirty Ductwork

If your ducts have leaks or aren’t appropriately sealed, dust and contaminants can enter your HVAC system, circulating throughout your home. This makes your AC dirty, reduces energy efficiency and can cause respiratory issues.

Prevention Tip: Have your ductwork inspected and cleaned regularly to ensure it’s properly sealed and free from dust buildup. A professional HVAC technician can detect hidden leaks and blockages. Schedule a duct inspection with Airview AC today!

4. Lack of Regular Maintenance

Skipping annual AC maintenance allows dust, dirt, and debris to accumulate inside your unit. Over time, this can lead to reduced efficiency, unexpected breakdowns, and higher energy bills. Neglecting professional servicing can also void your manufacturer’s warranty.

Prevention Tip: Schedule professional AC maintenance at least once a year. A trained technician will clean the coils, check refrigerant levels, and ensure all components function correctly. Book your AC tune-up with Airview AC now!

5. Moisture & Mold Growth

Air conditioners create condensation, which, if not drained properly, can lead to mold and mildew buildup. This impacts air quality and can clog your system and cause water damage.

Prevention Tip: Regularly check your AC’s condensate drain line for blockages and schedule professional cleaning to prevent mold growth. If you notice musty odors or excessive moisture around your unit, call Airview AC for a thorough system inspection.
